HKS 80015-AN101 Hipermax D' NOBspec Coilover Full Kit

The HKS Hipermax D' NOBspec coilover kit (PN: 80015-AN101) is a drift-engineered full suspension system developed in collaboration with Nobuteru Taniguchi, the first D1 Grand Prix champion. Rather than simply maximizing stiffness, HKS and Taniguchi conducted extensive real-world testing across multiple skill levels, analyzing load shift, traction, and weight transfer dynamics to engineer a coilover that makes drifting more accessible, progressive, and fun.

Key Features:

• Monotube (Single-Tube) Construction — A high-performance mono-tube damper design delivers superior heat dissipation, improved ride quality, and consistent damping response during aggressive driving.
• 30-Way Damping Adjustment (Front & Rear) — 30 individual compression and rebound settings allow precise tuning for a wide range of driving styles and track conditions.
• High-Flow Linear Piston — The linear progression piston optimizes oil passage control for smooth, consistent valve movement. As piston speed increases, damping force increases proportionally for predictable handling.
• PNE Coating — Provides corrosion resistance five times greater than standard galvanization. The ultra-smooth surface also reduces the friction required to adjust ride height, making setup changes easier than conventional dampers.
• 2-Way Pillow Ball (Spherical Bearing) Upper Mount — Front & Rear — Included spherical bearing upper mounts expand caster and camber adjustment range. Camber range: -2°45' to +5°05'. Compatible with inverted strut-type front dampers.
• Aluminum Lock Nut & Ride Height Adjuster — Anodized aluminum hardware resists rust and corrosion while reducing unsprung weight for improved suspension response.
• Standard Dust Boots — Factory-installed dust boots shield the damper shaft from road debris, rocks, and contaminants to extend component life.
• Height-Adjustable Lower Bracket (Front & Rear) — Front ride height adjustable range: 686mm–571mm. Rear ride height adjustable range: 677mm–583mm.
• Rear Helper Spring Included — Rear helper spring (19.8 N/mm) is included to maintain damper seating throughout the full range of suspension travel.
• Spring Rates — Front: 78 N/mm (8 kgf/mm) / Rear: 49 N/mm (5 kgf/mm). Free length: Front 170mm / Rear 200mm.
• 1-Year / 20,000 km Limited Warranty — Backed by HKS's standard limited warranty covering defects in materials and workmanship.

The Hipermax D' NOBspec is engineered to deliver championship-caliber drifting performance in a package accessible to drivers of all skill levels. Whether building a dedicated drift car or a dual-purpose street and track machine, this kit provides the adjustability and progressive damping characteristics required for confident, controllable oversteer.
